Wifi connection symbol TFT shield

-

hi all,

i have 3.5" tft display (ili9481) , esp8266 wifi module hooked mega.

my question is:

how create , display wifi connection symbol @ least shows arduino connected wifi , @ changes strength of signal?

i interested in how create symbols have got display working , figure out wifi side of things later.

thanks in advance input.

typically library let draw filled rectangle, can small represent "led" indicator on screen wherever like.

fill color change signal strength, red weak or no signal, orange, yellow , green representing increasing signal strength.
